Ecuador's largest refinery was knocked out of service Thursday due to a power cut, state-owned Petroecuador said.

Operations at the 110,000-barrel-per-day Esmeraldas plant - where a power failure in April had resulted in a week-long shutdown - were suspended around 9:00 a.m., a Petroecuador spokesperson told Efe.

Technicians were still analyzing where the power cut occurred and therefore it remains unclear when operations will resume, the spokesperson said, adding that the shutdown will not affect domestic consumption because Petroecuador has sufficient reserves to meet demand.

Ecuador consumes 60,000 barrels of gasoline daily, the CEO of the state-owned firm, Marco Calvopiña, said Thursday.

The country also has two other smaller refineries: La Libertad in the southwestern coastal region and Amazonas in the northeast.

Ecuador's crude output currently stands at 500,000 barrels per day and oil is the country's main export product. EFE
